1 Renesas Synergy MCUs Build Foundation for Groundbreaking Integrated Hardware/ Software Platform New family of microcontrollers combines scalability, power efficiency with extensive peripheral capabilities T he key to building a presence in a new market with an innovative new technology is to construct that technology on a solid foundation. For the Renesas Synergy Platform, that firm foundation is a new family of highly-scalable, compatible and power-efficient microcontrollers (MCUs). Designers eying new applications in the embedded and rapidly emerging IoT market need a highly-scalable, upwardly compatible family of MCUs that combines high-efficiency with competitive price/performance characteristics.

2 The Renesas Synergy MCUs are designed from the ground up to serve that purpose. Based on the ARM Cortex -M family CPU cores, these new microcontrollers combine extremely low power consumption with excellent deterministic behavior in a small package. Rich Connectivity Options The range of potential embedded applications for these new MCUs runs the gamut from simple tags designed to attach to a cow s ear to monitors in household appliances. Given the wide variety of application requirements, crafting the right MCU feature set is no small task. Some functions, however, clearly essential. One is connectivity. Most of the MCUs in the embedded market today supply a base set of peripherals including a wide array of connectivity options. Renesas Synergy MCUs take this one step further. The top-of-the-line Renesas Synergy MCU family, for example, offers dual Ethernet with IEEE-1588 synchronization, USB HS, plus many serial interfaces including UART, IIC, SPI, IrDA, QSPI, SSI, SDHI and CAN. As embedded and IoT applications move toward the edge of the network where systems are often measuring the environment, analog interfaces play an increasingly crucial role. To meet this need, Renesas Synergy MCUs add a full array of analog-to-digital and digital-to-analog converters, analog comparators and temperature sensors. In addition, Renesas Synergy MCUs add a variety of timing functions that are typically used in motor and industrial control applications. Scalability and Compatibility Time to market is a huge factor in any company s success. The ability to reuse hardware and software helps design teams shorten development time. Renesas Synergy MCUs are architected from the ground-up to provide seamless scalability and peripheral compatibility among products, enabling customers to extend software reuse by using common peripherals based on a consistent memory map. MCU scalability enables customers to easily migrate from one product to another in the same family or between families. And the use of a concentric package design allows customers to easily migrate from one package to another with minimum hardware changes. In addition, a common CPU architecture based on ARM Cortex -M CPU cores enables a seamless code migration across the entire Renesas Synergy MCU family. Taken together, these characteristics make Renesas Synergy MCUs a truly scalable and compatible solution, enabling customers to maximize reuse of software and hardware and, in the process, shortening development time and reducing time to market. 2

Focus on Security Given the fundamental role connectivity plays in every IoT design, solutions at every level of the network are vulnerable to malicious attacks.

Once the product goes into the field, hackers could replace firmware with malware or exploit a software update session to inject malware into a system.

Clearly product designers must address a wide array of potential security concerns, not only to ensure the integrity of their product, but also to reassure prospective consumers before they invest in

3 Focus on Security Given the fundamental role connectivity plays in every IoT design, solutions at every level of the network are vulnerable to malicious attacks. The threats can occur at every stage of the product lifecycle. During manufacturing, a less-than-honest employee could clone firmware or the security configuration of a product. Once the product goes into the field, hackers could replace firmware with malware or exploit a software update session to inject malware into a system. And if system parameters are lost, firmware could be susceptible to an eavesdropping attack. Clearly product designers must address a wide array of potential security concerns, not only to ensure the integrity of their product, but also to reassure prospective consumers before they invest in this new market.

4 To protect embedded systems from these threats, Renesas Synergy MCUs add significant security capabilities in hardware where they are less susceptible to attack. As an example, when each MCU in the Renesas Synergy product line is manufactured, it is assigned a 128-bit unique ID which can be used to generate keys to protect applications and assist provisioning. Renesas Synergy includes true random number generator on a chip for use with industry standard specifications such as NIST SP recommended deterministic random bit generators (DRBGs). Many of the MCU members also feature Memory Protection Units (MPUs) that can be used to read- and write-protect an area across the entire addressable memory map. Developers can use this feature to create a secure region that is protected from access by a rogue program. They also feature hardware accelerators for symmetric cryptography, asymmetric cryptography, and HASH. 4

5 Ultra-low Power S1 Series For the low power end of the market where many embedded and IoT solutions are expected to emerge, Renesas has selected the ARM Cortex -M0+ CPU core. Optimized for battery-powered applications, the ARM Cortex -M0+ core combines a state of the art low-power architecture with optimized low-power modes, faster wake-up time and low-power peripherals.
